How do you guys cover your boat for winter?

I use a tarp, but lay planks from the center console out to the gunwales of the master angler to shed and/or support snow. Not as maintenance free as the ridgepole designs once you get snowmelt, as it can collect. I worry about the point loading of some designs on the cap/gunwale.

I am considering skinning some pink styrofoam panels with glass to make sandwich cores as a light hard shell, over which I put a tarp. But haven't tried that yet.
